Once I had a very good friend, but since we had different opinions on the problem, we never talked to each other again and we lost our friendship. So I was wondering if the long time friendship existed. Later I met a new friend, we shared the same interest and she showed me the good qualities, such as patience and kindness. Sometimes when we had argument, she would not angry and left a while to let me calm down. Now I learn to be considerate. I cherish our friendship so much and I treat her as my lifetime friend. The good friendship should be maintained by each other.?
